With a design career spanning some 60 years, it's no surprise that Oscar de la Renta has amassed his share of inspiration sources. In his office at his New York City atelier, a bookshelf houses some of the designer's literary acquisitions. Floor-to-ceiling shelves overflow with fashion tomes in the graceful yet intentional manner tulle did from the gowns that closed his Spring 2014 show. His most-recently checked-out and latest additions casually lay horizontally atop tightly packed reads. At the top of the case, awards from the designer's lifetime of achievements stand on display. At the bottom, framed prints elegantly lean against it.
